There is no consensus yet among pterosaur researchers that all pterosaurs 
(or any) involved the fore and hindlimbs into a continuous flight surface. 
Though the continuous surface is certainly possible, several pterosaur 
workers see no evidence for it in the fossil record and think that the 
fossil evidence leans toward independent flight surfaces which would be far 
more effective for denizens of mostly marine soaring niches.
